i will say my adjustable a frame 22' ladder. i do a ton of commercial work so it is used quite often. lots of different height drop ceilings also..i only need this one to do it all not 2-4 different ones..
i put on on my 800-1000lb rated adjustable handtruck to roll it around..milwaukee used to make it...there is no damn way im lugging compressors and all recovery equipment through buildings..to get to the roof..
